Peakto's search function

Peakto's search function

I find it inconvenient that it isn't possible to just type a word or phrase in the search field and then press enter. It would be useful if there was a way of specifying a default setting for the search function so that you didn't have to scroll through the long list of options every time you search for something.

Say I want to find images whose metadata contain the word "London" or "winter" or "eating", regardless of where in the metadata the word is to be found. What do I do then in order to get the result I want in the quickest possible way?
